vw fox and audi fox exhausts swappable?

[SCIROCCO75 at aol.com (SCIROCCO75@aol.com)]

Hey all, my brother drives a 93 vw fox and its time for an exhaust system, I 
saw an audi fox supersprint exhaust on ebay and just wonder if anyone has an 
educated guess. I actually spent some time under audi fox's as a kid but can't 
really be sure if the underside of the cars are similar enough. Check this 
out, but outbid me!  Michael
